Abstract
Description
- The invention relates to a ventilation device, in particular to a ventilation device for a vehicle interior.
- Ventilation devices in motor vehicles are basically known. On the one hand, they are applied for ventilating the interior, and on the other hand are applied against a misting or a frosting of the window panes (defrost function), above all of the window panes in the front region. Ventilation devices are for example integrated into the interior as a constituent part of an instrument panel.
- A ventilation device which includes a defrosting function as well as a direct ventilation of the interior, is disclosed in DE 102 19 053 A1.
- This ventilation device contains an air feed channel as well as an outflow region for ventilating the interior. A first and second component is provided in the outflow region, which may be brought into different conditions of displacement relative to one another. In each case, different closure surfaces of the first and second component bear on one another in the different conditions of displacement. Airflows into the interior with different outflow angles may be released by way of this.
- Advantageously, at least two displacement conditions may be set, wherein an airflow is directed to the windscreen in the second displacement condition, and the airflow is directed to a greater extent towards the centre of the vehicle interior in the first displacement condition.
- The disadvantage of this ventilation device is the fact that the airflows, although being able to be orientated in a coarse manner, for example on the one hand in the direction of the windscreen and on the other hand in the direction of the centre of the interior, however a more sophisticated guidance or control of the airflow is not present.
- In particular, it is difficult with such a ventilation device, on the one hand to produce an adequately large airflow in the edge region of the window panes, in order to prevent or alleviate misting, and on the other hand to direct the airflow into the interior, such that this does not act in a disturbing manner with regard to the driver or front seat passenger.
- It is therefore the object of the present invention, to provide a ventilation device which effects an advantageous formation of the airflow, in particular may be applied on the one hand for the direct ventilation of an interior of a vehicle, and on the other hand for the ventilation of a windscreen of the vehicle.
- This object is achieved by a ventilation device according to the independent claim 1.
- Two airflows which are completely different with regard to their outflow behavior may be realized by way of the fact that the first component or the second component comprise a first lamellar structure, and the first or the second component comprise a second lamellar structure which differs from the first one, and that in the first displacement condition of the first and second component, air may flow out through the first lamellar structure for producing a first airflow with a first opening angle, and in the second displacement condition, air may flow out through the second lamellar structure for producing a second airflow, at a second opening angle which is different form the first one.
- The opening angle of the airflow is defined by the orientation of the lamellae belonging to the lamellar structure, and the air passage gap produced by way of this. If for example, the lamellae of a lamellar structure are orientated parallel to one another, then a directed airflow having a negligible opening angle may be produced. If the lamellae of a lamellar structure are fanned-out, then a fanned-out airflow having an opening angle according to the degree of fanning-out of the lamellae may be produced.
- The ventilation device according to the invention combines two different lamellar structures, in order to realize two different airflows. In particular, the lamellae of the lamellar structures are arranged in a fixed/unmovable manner in the respective component. A mechanism for tilting only the lamellae, in order to change the airflow, as is known for example with side blowers in instrument panels, is no longer necessary due to this combination of different fixed lamellar structures.
- Advantageous further formations of the invention are described in the dependent claims.
- One advantageous further formation of the invention envisages the first lamellar structure comprising lamellae lying parallel to one another, and the second lamellar structure having lamellae tilted to one another in a fanned manner, and air being cable of flowing out through the first lamellar structure in the first displacement condition of the first and second component, for producing a first, directed airflow, and air being able to flow out through the second lamellar structure in the second displacement condition, for producing a second fanned-out airflow.
- The application of such a ventilation device in the interior of a motor vehicle is particularly adjacent to a windscreen, in particular as a constituent part of an instrument panel. With the fanned-out airflow, which may be produced by way of the ventilation device, one may adequately subject the windscreen to airflow over the complete width. With the directed airflow which is produced by the first lamellar structure, one may deflect air into the interior in a targeted manner, without disturbing a driver or front seat passenger. In particular, one may apply a ventilation device according to the invention in a significantly reduced width with respect to conventional ventilation devices, without entailing disadvantages with regard to the defrosting function.
- Here, fan-like is to be understood in that adjacent lamellae of the second lamellar structure are tilted to one another. The degree of tilting thereby increases to the next neighbor of a lamella, to the next but one neighbor, etc. However “fanned-out” is also to be understood if only certain regions of the lamellar structure have this arrangement, or individual lamellae within such a region do not follow this behavior. For example, a lamellar structure with three adjacent regions, wherein several lamellae which are aligned at a first angle are provided in the middle region, several lamellae which are arranged at a second angle which is positively tilted to the first angle, are provided in the left edge region, and likewise several lamellae which are arranged at a third angle negatively tilted to the first angle are arranged in the right edge region, is also likewise to be understood as “fan-like”.
- Moreover “fan-like” is only to be understood as those lamellar structures which effect a fanning-out of the air with an opening angle of at least 10°, preferably at least 30°, or whose air passage gaps defined by the lamellae are tilted by a maximal angle of at least 10°, preferably 30° (in the case of a “uniform” fanning-out, this angle would be defined by the tilting of the two gaps lying on the edge side).
- The lamellae are preferably planar plates or platelets. This permits large air gaps and thus a large air passage through the lamellar structure. Alternatively, the lamellae may also be designed as compact, solid webs, whose side surfaces are angled in a manner in order to produce a directed and fanned-out airflow.
- One further advantageous formation of the invention envisages the first and the second lamellar structure being grid-like.
- According to the invention, a multitude of lamellae are provided, which are arranged in a planar manner in several parallel rows at defined distances.
- One further advantageous formation of the invention envisages in each case different closure surfaces of the first and the second component bearing on one another in the different displacement conditions of the first and second component, for realizing different outflow angles of the airflow, additionally to the fanning-out and directing.
- According to this advantageous further formation, it is possible for example in the case of a ventilation device applied in an instrument panel, in the first displacement condition, to guide the directed airflow more into the interior of the vehicle, and in the second displacement condition to guide the airflow directly against the windscreen.
- One further advantageous formation of the invention envisages the first component and/or the second component comprising prismatically, preferably triangularly shaped webs.
- In particular, the outflow angle is defined by the sides of the prismatic webs.
- A further advantageous formation of the invention envisages the prismatically shaped webs being arranged in a common plane and parallel to one another, and, arranged one after the other between two adjacent webs, a first lamellar structure and a second lamellar structure with lamellae aligned perpendicularly to the parallel webs.
- The lamellae of the second lamellar structure are thus fanned-out parallel to the webs.
- The elements in the sequence web-first lamellar structure-web etc., are preferably arranged within a common plane.
- One may realize a particularly flat and compact constructional shape with these features.
- The term “plane” in this context is also to be understood as a slightly arcuate surface, for example the slightly curved surface of a part of the surface of an instrument panel, said surface being adjacent to a windscreen.
- One further formation of the invention envisages the first component and/or the second component comprising grooves or recesses, in which the lamellae of the first and/or the second lamellar structure of the other component are at least partly guided.
- By way of this, in particular one may ensure that the first component and the second component may be displaced to one another exclusively along a predefined path.
- A further advantageous formation of the invention envisages providing a third component, which for closing the outflow region, is movable independently of the movement conditions of the first and the second component.
- Alternatively, by way of forming closure surfaces on the first and/or the second component, one may also realize a third displacement condition in which the outflow region is closed.
- The invention is hereinafter explained by way of one embodiment example including several Figures. Thereby, there are shown in:

FIG. 1 shows a first component and second component, belonging to a ventilation device according to the invention, in this example designed as a shutter 1 orprism grid 2. - The shutter 1 is shown in
FIG. 1 in a view to the viewed side. It is designed as a planar, elongate element with three rectangularelongate ventilation slots 15 which run parallel to one another. The material of the shutter 1 is plastic. - The
prism grid 2 is likewise shown in a plan view. Corresponding to the shutter 1, theprism grid 2 is designed as an elongate, planar component. - The
prism grid 2 comprises threeelongate webs 5 which are arranged in a common plane and parallel to one another. Thewebs 5 have a prismatic shape, in this embodiment example a triangular shape, in their cross section (XY-plane). Additionally, thewebs 5 are hollowed out at the rear side (seeFIG. 3 ). - In each case, a first
lamellar structure 3 and a secondlamellar structure 4 are arranged one after the other (X-direction) between thewebs 5. In each case, alamellar structure outermost webs 5. - The first
lamellar structure 3 and the secondlamellar structure 4 in this case consist of a multitude of grid-like lamellae which are arranged next to one another at defined distances. The lamellae themselves are formed as planar platelets. Thereby, the lamellae of the firstlamellar structure 3 are aligned parallel to one another (XZ-plane). The secondlamellar structure 4 in contrast comprises lamellae which are tilted to one another in a fan-like manner. - In this embodiment example, the fanning-out of the lamellae of the second
lamellar structure 4 is selected such that the lamellae located in the middle of theprism grid 2 are arranged in a common plane (XZ-plane) with the lamellae of the firstlamellar structure 3, but the adjacent lamellae of thelamellar structure 4, proceeding outwards (Y-direction) from the middle of theprism grid 2, are tilted at a positive and negative angle to an ever increasing extent about the X-axis. The maximal angle, with which the respective outermost lamellae of the secondlamellar structure 4 are tilted to one another, is about 70° in this embodiment example. This angle is of course dependent on the application purpose, thus may vary widely. - Lamellae of the first
lamellar structure 3 and of the secondlamellar structure 4 are in particular aligned perpendicularly (YZ-plane) to theparallel webs 5. - The material of the prism grid is likewise plastic.
- Alternatively, metal or a combination of metal and plastic may be applied as a material for the shutter 1 and the prism grid 1.
-
FIG. 2 shows the lower side of the shutter 1. - The lower side of the shutter 1, in contrast to the flat viewed upper side, has a grid-like structure. The structure of the lower side of the shutter 1 consists of a multitude of
blocklets 16. Theseblocklets 16 are integrally formed in the shutter 1 as one piece. - This grid-like structure is designed such that the
prism grid 2 may be accommodated and guided in this. The height of the structure thereby corresponds roughly to the height of theprism grid 2. Moreover, the structure of the lower side of the shutter 1 comprisesrecesses 8, into which the lamellae of the firstlamellar structure 2 and of the secondlamellar structure 4 are guided, for this, seeFIG. 3 . In particular, this permits the structure of the shutter 1 to bring theprism grid 2 arranged in this structure, into a first displacement condition, in which the lamellae of the firstlamellar structure 3 are located below theventilation slots 15, and by way of displacement, to bring the prism grid into a second displacement condition, in which the lamellae of thelamellar structure 4 are arranged below theventilation slots 15. - As is to be seen in
FIG. 3 , as a rule, in each case ablocklet 16 is located between two adjacent lamellae. Theblocklets 16 fill out a large part of the volume between the webs with the exception of therecess 8 which is required for the guidance of the lamellae, so that air may be led directly through theventilation slots 15 without swirling to much within the structure. - Moreover, the side surfaces 7 a and 7 b of the
blocklets 16 which lie adjacent to theventilation slots 15 are designed to match the side surfaces 6 a and 6 b of thewebs 5 of theprism grid 2, so that in each casedifferent closure surfaces blocklets 16 andwebs 5 bear on one another in the first and second displacement condition, by which means a different outflow angle of the air flow may be produced, additionally to the fanning-out or directing, which are effected by the arrangement of the lamellae. This principle is explained at a later point in time. -
FIG. 4 shows a ventilation device according to the invention, in a first displacement condition. However, the representation is limited to the ventilation cassette, consisting of the shutter 1 and theprism grid 2 arranged below the shutter 1. The air feed channel and the outflow region which are not shown here, lie below theprism grid 2. Air may be led through the air feed channel into the outflow region, and from there, through the ventilation cassette which consist of the shutter 1 andgrid 2, and which is arranged above the outflow region. Any systems, particularly those used in the automobile industry, may be applied as an air fed channel and outflow region. - One may easily recognise in
FIG. 4 , that it is exclusively the firstlamellar structures 3 which are located below thelongitudinal slots 15. If air flows through this ventilation cassette, then a first directedairflow 13 is produced. -
FIG. 5 shows the ventilation device in the second displacement condition. - In this displacement condition, only the
second lamellae structures 4 with their fanned-out lamellae are located below theventilation slots 15 of the shutter 1. If air flows through the ventilation cassette, then a second, fanned-out airflow is produced. -
FIG. 6 shows a ventilation device according to the invention, integrated into an instrument panel of a vehicle in the first displacement condition. - In this embodiment example, the ventilation device according to the invention (more accurately: the shutter 1), is arranged adjacent to a
windscreen 11. The shutter 1 thereby, with regard to its dimensions, assumes the middle third of the surface of the instrument panel. - As is seen in
FIG. 6 , afirst airflow 13 is produced by the ventilation device according to the invention, and this airflow is directed directly into theinterior 9 of thevehicle 10. The angle at which the air flows out, is thereby selected such that theairflow 12 may go through and between the driver and front seat passenger in an essential directed manner. The opening angle of theairflow 13 which is set by the lamellae of the firstlamellar structure 3, is negligible small. -
FIG. 7 shows a ventilation device according to the invention, integrated in an instrument panel of a vehicle in the second displacement condition. - In this example, the ventilation cassette with the shutter and the
prism grid 2 is designed such that in the second displacement condition, a fanned-out airflow is produced, which, in contrast to thefirst airflow 13 produced in the first displacement condition, is guided directly against thewindscreen 11 of thevehicle 10. Due to the effect of the fanning-out of the airflow, it is particularly the case that thewhole windscreen 11 is affected, by which means one achieves a complete defrosting. The opening angle of the airflow which is defined by the lamellae of thelamellar structure 14, is about 70°. - Alternatively to the embodiment of a ventilation device according to the invention described here, both
lamellae structures - Moreover, additional further lamellar structures may be integrated in a ventilation device according to the invention.
- Hereinafter, it is explained in more detail how airflows with different exit angles may be produced in the first and second displacement condition.
- For this,
FIG. 8 shows a schematic cross-sectional view of a ventilation device according to the invention, in a first displacement condition. - However, only the
blocklets 16 of the structure of the lower side of the shutter 1 and thewebs 5 of theprism grid 2 are shown. The plane of the cross section is the XZ-pane, cf.FIG. 1 . - In the first displacement condition, a
second side surface 6 b of aweb 5 bears on asecond side surface 7 b of ablocklet 16. A gap through which the air may flow arises between afirst side surface 6 a of theweb 5 and afirst side surface 7 a of theadjacent blocklet 16, which lies opposite thisside surface 7 a. The orientation of the side surfaces 7 a of theblocklet - The
webs 5 may be brought into the second displacement condition by way of displacing theprism grid 2. -
FIG. 9 shows a schematic cross sectional view (XZ-plane) of an ventilation device according to the invention, in the second displacement condition. - In the second displacement condition, a
first side surface 6 a of aweb 5 lies on thefirst side surface 7 a of ablocklet 16. A gap through which the air may flow out, is formed between thesecond side surface 6 b of theweb 5 and thesecond side surface 7 b of theadjacent blocklet 16. The shape of the gap thereby is given by the geometry of the side surfaces 6 b and 7 b. In this case, the side surfaces 6 b and 7 b are designed such that a gap parallel to the Z-direction is formed, through which an airflow which is essentially parallel to the Z-direction may be produced. - In this embodiment example, the
webs 5 are triangular in their cross section and theblocklets 16 are rectangular. Basically here, also other shapes, for example webs with rectangular cross section and blocklets with a triangular cross section, as well as basically different shapes may be applied. - Apart from the shutter 1 and the
prism grid 2 shown here, the ventilation device may also contain a third component, with which theventilation slots 15 of the shutter 1 may be closed. One possible embodiment of such a component would be a planar element withventilation slots 15 dimensioned according toclosed surfaces 15 which by way of displacement may be brought into congruity with theventilation slots 15. - Alternatively, it is also possible to integrate such a function in the
prism grid 2. For example, a closed surface may be provided between thewebs 5, which may be brought into congruity with theventilation slots 15 by way of displacing theprism grid 2.
